The main reason that you wouldn't want an orange or red binocular for birding is birds can see in color as we do and probably better.
I hunt wild turkey and they can see colors at incredible distances.
I would not mind an orange binocular for hunting but wouldn't have much success with it...
I looked at a 10x42 NL at Cabelas and thought they were fantastic.
I noticed the huge FOV and clarity right away.
I will probably get the 12x42 NL since I have the 10x42 HT.
Don't really need the NL since my HTs are just fine but can't stand not owning the latest and greatest.
I never once...
I have a pair of the Swarovski SL seen in post #3.
I bought them in 1989 and loved them despite their heavyweight construction and terrible focus wheel.
To me, they're by far the best-looking and rugged porros ever made.
I gave them to my cousin several years ago but he despised their weight...
